This goal of this study was to evaluate the effectiveness of a new coagulant extract from pumpkin seeds (PSC) for removing turbidity and organic compounds from different natural surface waters. Two design experiment methods, namely central composite design (CCD) and response surface methodology (RSM...

The primary purpose of this study is to investigate boron removal from synthetic hydraulic fracturing wastewater by membrane processes. The effects of pressure, pH, feed concentration, and polyol concentration on boron removal were determined using a cross-flow, flat-sheet membrane test unit. The...

Kalamata’s decentralized waste management and composting scheme is a successful demonstration of the capacity of a municipality to manage its Municipal Solid Wastes (MSW) by adopting methodologies that can be supported by small scale mobile equipment. According to the revised legislation, Join...

Regular water treatment-plant (WTP) comprises of a number of units. Of course, problems exist throughout design and operation of the WTP units. Consequently, the current re-search aimed to minimize the shortcomings of the coagulation, sedimentation, and the adsorption methods through applying...

The calcined clam seashell powders were applied as adsorbent to adsorb Dibutyl phthalate (DBP), from an aqueous solution. The influence of calcination conditions including temperature and time on its adsorption capability to DBP was investigated. The shell powders calcined at 500 oC had the best...

Volatile Organic Compounds (VOCs) are toxic for the environment and human health and their tendency to readily volatilize in the atmosphere can lead to problems connected to odours annoyance. Conventional VOCs gaseous emissions treatments entail the application of chemical-physical processes, only...

In the recent era, utmost attention is paid towards exploring the alternative source of energies, being more specific green energies. In modern days, when growing energy scarcity is a hot topic and considered as a global threat, in that context a green technology capable of sustainably addressing...

The objective of this work was to determine the composition and production rate of cytostatic pharmaceutical waste produced by Theagenion Cancer Treatment Hospital (TCTH) in Thessaloniki, Greece. This information is necessary for the design and costing of management systems for cytostatic...

Odour emissions from industrial plants affect air quality and are consequently cause of a growing number of public complaints. The control of odour represents a key issue in plant management. The starting point for an effective odour control is their objective measurement. The electronic nose...

The purpose of the study was to improve drinking water quality of conventional treatment processes by combining with UF-membrane systems. Performances of two membrane systems were evaluated in two different full-scale conventional water treatment plants in Istanbul. Low-pressure UF membranes were...

Sludge is the ultimate by product of all traditional and conventional wastewater treatment processes. Conversion of the treatment sludge into new products is a significant disposal alternative for these wastes. In this study, branches, leaves and the organic and inorganic trash coming out from the...

Advanced oxidation processes (AOPs) have led the way in the treatment of aqueous waste and are rapidly becoming the chosen technology for many applications. In this paper, COD reduction of textile industry wastewater by electro-Fenton (EF) oxidation, was studied at batch experimental conditions. The...

Solar simulated heterogeneous photocatalysis (SSHP) with suspended TiO 2 was investigated in the inactivation of tetracycline resistant/sensitive Enterococcus (TRE/TSE) strains in the effluent of an urban wastewater treatment plant (UWTP). The effect of solar simulated disinfection (SSD) on the...

The present work is about the techno-economic evaluation of a biodiesel industrial unit that exclusively use recycled edible oils as feedstock, for two alternative production technologies. Nowadays, many biodiesel production units use a mixture of virgin vegetable oils and waste cooking oils. The...

The Soil Science Institute of Thessaloniki produces new digitized Soil Maps that provide a useful electronic database for the spatial representation of the soil variation within a region, based on in situ soil sampling, laboratory analyses, GIS techniques and plant nutrition mathematical models...

The objective of this research is to show how sediment micro-pollution, including heavy metals, hydrocarbons and PAHs, can be reduced by means of a physical treatment based on screening and attrition. The study was carried out on five stormwater sediments, the developed pilot unit allows to isolate...

Foaming and bulking problems in activated sludge treatment plants are associated to the presence of a variety of filamentous bacteria. However, it has been observed that M. parvicella is the most frequent filamentous microorganism causing sludge bulking and foaming, especially in treatment plants...

This paper aims at a comparative evaluation of the total cost of urban sewage processing units for several treatment systems, appropriate mainly for small capacity plants. The studied systems are: Oxidation Ditch (O.D.), Trickling Filter (T.F.), Rotating Biological Contactor (R.B.C.), Compact...
